OrionIR® Mid-IR Spectrometer
Real-time chemical composition, measured in the process
At 5 × 5.5 × 6 cm the OrionIR® is a fraction of the size of a traditional spectrometer. It uses no moving components and no fragile optical fibres, so you decide where and how it is deployed.

The OrionIR® family
One measurement principle, four builds. Pick the one that matches where the instrument has to sit, then open its specifications.
Lab version
The published standard build
Hand-tight 1/4"-28 fittings, 0–5 bar, USB-C for power and data. Every number on the specifications page describes this build. Bench work, development and pilot rigs.
Specifications
High-pressure version
For a pressurised line
The same optics and the same flow cell, rated to 40–50 bar rather than 5, for a process line that cannot be let down to atmospheric pressure to be measured.
Specifications
TEC version
For a temperature-held sample path
Thermoelectric control holds the sample path between 15 and 55 °C, for chemistry whose spectrum moves with temperature or a stream that must not cool in the cell.
Specifications
Plant version — in development
For a production line
Built for plant flow rates — around 30 L/min, up to a 1-inch pipe — with an Ethernet connection and EMA ICH Q7 as its GMP reference. Not yet released.
What is known so farWhy mid-infrared, and why transmission
Dipole moments in molecular bonds vibrate at energies that correspond to the mid-infrared region, so light passing through a sample is absorbed by the bonds that match in energy. Because those dipole moments are affected by the bond and by its surroundings, mid-IR spectroscopy identifies what is present and how much of it there is.
Measuring in transmission — rather than at a probe surface — is what lets the OrionIR® read strongly absorbing and aqueous streams that saturate a longer path. The short optical path does the work: 20 µm as standard in the 900–1800 cm⁻¹ range, with 100 µm and 200 µm options, and 25 µm as standard in the 1800–3500 cm⁻¹ range. The measurement is non-destructive, so sample integrity is preserved for further testing or downstream analysis.
What you get out of it
- Track reactant and product concentrations live, at every stage of development and production.
- Optimise reaction conditions with precision instead of by fixed time.
- Detect deviations and side reactions early.
- Accelerate development and troubleshooting.
- Hold product quality and performance consistent.
- Detect low concentrations of reactants and products reliably.

How it works
Getting to a number, not a spectrum
A spectrum is not an answer. We build the chemometric model that turns it into concentration for your specific chemistry.
-
01
Plug in
Connect the module by USB to a computer with the software installed — in the lab or in the field.
-
02
Measure on the loop
A 0.1 mL flow cell on a recirculation loop. No grab sample, no lab trip, no quench.
-
03
Calibrate to your chemistry
We build and integrate calibration models directly into the software platform, so the readout is concentration.
-
04
Act on it
Live data enables instant adjustment of reaction conditions for better control and faster optimisation.
User guide
Setting it up, and the first measurement
Unpacking, connecting and the first run — then taking a chemical background and measuring a sample, which is where most first-hour questions actually are.
